﻿This folder contains data and MATLAB script to create plots in the paper. Abbreviations refer to two separate C19th newspapers: GCLN = The Graphic, IPNW = Illustrated Police News.

[-] code - contains MATLAB scripts to create plots.
		Run_plotRatioVSYear.m - create plot image to text ratio over years on GCLN
		Run_show_halftone.m - create plot of halftone images over time on GCLN
		Run_show_lowlevel.m - create plots of pixel ratio to entropy on GCLN, IPNW
[-] data - contains data to create plots
[-] figs - plots used in the paper
